To me it sounds like autistic burnout. I have it from taking 18 credits of college classes. Nearly broke down in chior for no reason. It can be caused by persistant stress that can be small in nature, or lack of sleep, or many other things This leads to the frequent meltdowns which is overload. So more meltdowns means you are being overloaded more. So the main thing it to eas up a bit. It is common for adults to have. This is from what I can see so I could be completely wrong, but from my experience with it it is burnout.
